Accidentally announced too early, before the promotion was available, Sony Ericsson's free 50 GB Box cloud storage promotion, worth of US$ 19, is now available to all Xperia users which install the Box client from the Android Market and sign-in after from their Sony Ericsson Xperia device. Box, which comes with initial 5 GB of free storage space, is another cloud service which lets users view and share files from anywhere. It provides simple and secure sharing, letting users easily store files online, send big files fast, gives access from Android phones or tablets and the web and allows to collaborate with others.

Best of all, it's not available to new Xperia Box users only but to all Xperia users, even if they already have an account. After the login, the account is automatically upgrade to 50 GB.
